As in Section REF  simulated light curves were used to determine the response to transits. Assuming the mass–radius relationship for pure water planets at \(T=1000\)  K given by [1]} the expected maximum (\(b=0\) ) transit depths are \(\sim 600\)  ppm, (solid cyan lines in Figures REF g–i), and would be detected if present. To be consistent with no detected signal, \(b>0.97\)  (dotted lines in Figure REF g–i; Table REF ).
